Abstract
A 72-year-old man had a total gasteroctomy for gastric cancer when he was 67 years old. S-1 adjuvant chemotherapy was continued for two years. Four years after the gastrectomy, on abdominal CT scan, a cystic tumor in the tail of the pancreas was detected. On follow-up, the tumor was found to have increased in size ; a tentative diagnosis of intraductal papillary mucinous carcinoma was made, and a distal pancreatectomy with splenectomy was performed. On histopathology, a pancreatic tumor that was the same type of adenocarcinoma as the previously diagnosed gastric cancer was found ; the final diagnosis was pancreatic metastasis from the previously diagnosed gastric cancer. Pancreatic metastasis from gastric cancer is rare. It is thought that very few cases are candidates for surgery. Herein, we report our case with a review of the literature.
